Is my 390x good enough to max 1440p wow?

Hey all

Just wondering why i can't seem to get good frames in WoW

PC Specs are


Sapphire R9 390x Nitro

16gb Ram

on a 1440p 144hz monitor BenQ XL2730Z

Do have a second monitor 1920x1200

If i try max all the settings in wow my frames drop like sub 30

Linked are the settings i have to run atm for it to be playable
